He's no longer Mr. Elephantitis (ok, he'll always be Mr. Elephantitis). But I went and had a conversation with him and found out the following - his name is Willie, he's 56 years old, he lives around the corner, and his birthday is March 23rd. A band played for him on the street for his birthday, and he says he'll be out there every day til he's 90. And he's now famous! Obviously the sign was created by an admirer :)
